text: Lewis is a proponent of development imaging tools for use in personalized medicine. Lewis designs and develops radiochemical probes for use in nuclear medicine as well as multi-modality molecular imaging. The use of these probes span from oncological metabolic detection to understanding the biological processes of cancer and pharmacological modification. These probes can be used for biomarkers in clinical trials as well as used as an agent for oncological diagnostics. He has developed multiple new small molecules that target tumor metabolism, as well as radiolabeled peptides and antibodies for use in probing overexpression of receptors and antigens on tumors for research, clinical trials and in the clinic.
